TAPE-GUIDIN G MEANS FOR GO0DS-ROLLING MACHINES.

Specification of Letters Patent.

Patented Aug. 6, 1912.

Application filed December 20, 1911. Serial No. 866,998.

Goods-Rolling Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to cloth rolling machines, and has particularreference to machines of this class adapted for the doubling and foldingor the rolling of double width cloth into bolts, but is not restrictedto such use as the features thereof may be used in any connection forwhich they may be adapted or appropriate.

One object of my invention is to improve upon the mechanism describedand claimed in my former United States Letters Patent No. 962,193, datedJune 2]., 1910,for feeding a measuring tape between the folds of thegoods during the winding thereof in rolls or bolts, whereby to reduce toa minimum the liability of breaking the tape during an operation of themachine, increasing its efficiency of operation, and enhancing thepracticability and commercial value thereof.

In the use of machines of this character it has heretofore been thepractice, so far as I am aware, to wind the cloth in flat form upon flatcore members, such as wooden boards, or the like, the members beingcontinuously rotated atsubstantially uniform speed during the windingoperation, thus imparting an irregular pulling or jerking action to thecloth, which causes a wrinkling and uneven winding thereof, especiallyduring the initial portion of the winding of a bolt. This jerking actionalso causes a frequent breaking of a measuring tape being wound with thegoods.

An object of my invention is to provide an improved process and meansfor winding cloth upon bolt boards or cores whereby the cloth may bewound thereon in substantially cylindrical form and then removed fromthe winding mandrel and collapsed or flattened upon a core piece whichis disposed therein during the winding operation, thus avoiding theobjections above noted.

The invention is fully described in the following specification, andwhile the fea tures thereof in their broader aspects are capable ofembodiment in numerous forms, a preferred embodiment thereof isillustrated in the accompanying drawings, in which,

Figure 1 is a plan view of a machine embodying the invention. Fig. 2 isa front end elevation thereof. Fig. 3 is an enlarged plan of a portionof the guide bar over which the measuring tape is fed between the foldsor strips of the goods being rolled. Fig. 4 is an enlarged sideelevation of a portion of the mechanism for guiding and controlling themovements of the measuring tape. Fig. 5 is a cross-section thereof onthe line x x in Fig. 4. Fig. 6 is a detail partly in section of thesectional spool on which the measuring tape roll is mounted when placedin the machine. Fig. 7 is an enlarged perspective View of a portion ofthe tape guiding mechanism. Fig. 8 is a longitudinal section ofthe'winding mandrel in collapsed position with the cooperating expandingwedges in association therewith and one in section. Fig. 9 is a similarview thereof with the mandrel expanded and partly in section. Fig. 10 isan end view of the mandrel carrying a core member with a quantity ofgoods wound thereon. Fig. 11 is a perspective view in collapsed orflattened form of a core member comprising one feature of my invention,and Fig. 12 is an end view thereof in collapsed state with a quantity ofgoods wound thereon.

In illustrating the features of my invention I have shown them inassociation with a well known type of cloth doubling and foldingmachine, in which 2 is a drum under which the cloth or goods passes tothe winding parts after being doubled by the means provided for suchpurpose, 3 the shaft of such drum which is journaled at its ends insuitable bearings in the side frame pieces or standards 4t, 4t, and 5, 5are the shaft sections which are provided with suitable means forgripping or engaging the part or means upon which the goods is wound,said shafts being suitably journaled in axial alinement in theoppositeframe pieces 4, 4 and driven at uniform speed from a drive shaft 6 bysuitable chain and sprocket or,other suitable connection therebetween.One of the shaft sections 5 is mounted for free reciprocal movements inits bearing to adapt it to be axially moved relative to the other shaftsection to engage or release the goods winding member or mandrel carriedtherebetween, longitudinal movement for such purpose being impartedthereto by the turning of a screw 7, which is anchored in a stationaryframe part of the machine and is threaded through an arm 8 which fixedlyprojects from the movable shaft section, as shown in Fig. 1.

9 designates the usual guide bar, which projects from one side piece ofthe frame laterally of the machine in advance of the drum 2 in positionfor its free end to work between the folds of the goods prior to theengagement thereof with said drum as is Well understood in the art.Mounted for longitudinal reciprocal movements on the top of the bar 9 isa tape guiding strip 10, which has its upper surface preferablychanneled, as shown in Figs. 3, L and 5, and is provided in the base ofits channel with a longitudinally extending groove 11 through which aretaining screw 12 freely projects and threads into the bar 9.Projecting downward from the side edges of the guide strip 10 forsliding movement along the bar 9 are a pair of arms 13, which areconnected at their lower ends beneath the bar 9 and carry a swivel toothor tracer 14 Fig. 4 for working in the grooves of a multiple returngroove cylinder 15, which is suitably mounted in bearing arms 16 projecting downward from the bar 9. The cylinder 15 has slow rotationimparted thereto from the drive shaft 6 through any suitableintermediate gearing or connection, as best shown in Fig. 2, saidconnection in the present instance comprising a belt 17, which connectsa small pulley 18 on the shaft 6 to a larger pulley 19 on a shaft 20,and a small sprocket wheel 21 on the shaft 20, which is connected by asprocket chain 22 to a larger sprocket wheel 23 on the cylinder 15. Itis apparent with this mechanism that when a machine is in operation thecooperating action of the grooved cylinder 15 and tooth 14; will imparta slow reciprocal movement to the tape guiding strip 10 for the purposehereinafter described. The tooth 14: is yieldingly held in engagementwith the grooves of the cylinder by a coiled expansion spring 24 whichis mounted-in a socket therein and has its upper end thrust against thebar 9, as shown in Fig. 5.

The channel of the tape guiding strip 10 is closed at its top by an armor capping strip 25 which is preferably hinged to the free end portionof the guide bar 9, as at 26, to enable it to be raised from over thestrip 10, and is of sufficient length to extend substantially the entirelength of the guidestrip 10 when resting thereover. A catch 27 ispivoted to the inner end port-ion of the bar 9 and is adapted toreleasably cooperate with a pin projecting from a side of the free endportion of the arm 25 to retain such arm in closed position, as bestshown in Fig. 4:.

The roll 29 from which the measuring tape 30 unwinds is carried by asuitable spool, the shaft ends or trunnions of which are mounted inbearing slots 31' provided in the bearing arms or standards 32, '32.

which rise in laterally spaced relation from the inner end portion ofthe bearing arm 9, or stationary part 9 from which it projects. Thebearing arms 32, 32 are preferably of a yielding or flexible nature tofacilitate a relative lateral adjustment thereof as the width of thetape roll may require. A bolt 33 connects the upper ends of the bearingarms 32, 32 to facilitate an adjustment thereof. The bearing slots 31 ofthe bearing arms 32 are of suitable form to permit a quick insertion orremoval of the spool trunnions therefrom.

It is found in practice that it is quite important to the proper feedingof the tape to the goods that some means be provided for acting thereonafter unwinding from the tape roll 29 to resist a too free feedingthereof to the cloth. For this purpose I interpose a plurality of tapeguiding rolls between the tape roll 29 and its point of entrance to theguide strip 10, said rolls being alternately arranged to guide the tapeto have a zig-zag course of movement. These guide rolls comprise lowerand upper sets 34 and 35, respectively, the rolls of the lower set beingsuitably journaled in a carrying chair or frame part 36, which ismounted upon the top edge of the inned end portion 9 of the guide bar 9,while the rolls of the upper set are carried by bearing arms 37 whichare pendently attached to a flexible carrying bar 38. The bar 38 ishinged to one end portion of the frame part 36, as at 39, and isprovided at its opposite end with a catch 40 or other suitable means forreleasably engaging the associated end portion of the frame 36. hen thebar 38, which carries the set of rolls 35, is in the closed positionshown in Fig. 7 its rolls alternate with the rolls 34 and extend belowthe plane thereof whereby a passing of the tape over the rolls 3 1 andunder the rolls 35 causes the same to have a zig-zag course of movement.The bar 38, which carries the rolls 35, is preferably of a flexiblenature to allow it to have a springing action as the tape is drawnbetween the coacting sets of rolls, as it is found that the action ofthe tape feeding means is improved by this arrangement.

The tape 30, after passing through the channel in the guide strip 10,extends down ward over the outer end thereof through a reglsterlng openng in the guide bar 9 and is given a quarter turn, as indicated at 30,-

due to its passage through a narrow slot which is provided in a guidingmember 41 attached to the bar 9, as shown in Fig. 2. The tape thenpasses with the goods under the roll 2 and is wound therewith upon themandrel or other winding part of the machine. The openings in the bar 9and member l1 through which the tape passes in its downward course fromthe guide strip 10 are of suitable length to permit a lateral movementof the downwardly extending portion of the tape therein lengthwise ofthe bar 9 as the guide strip 10 is moved by the grooved cylinder 15 forsuch purpose. The moving. of the tape in this manner causes adistribution of the tape throughout a predetermined area of a rolllengthwise thereof to prevent the ridge which would be formed thereby inthe roll if the tape wound in the same plane thereon. With thisarrangement no ridge occasioned by the winding of the tape within thegoods is perceptible in a complete roll.

The spool upon which the tape roll 29 is mounted is shown, in thepresent instance, as comprising the two sections 42 and 43 which havecooperating telescoping hub portions 44 and 45 respectively projectingfrom their inner sides, and each has a trunnion 46 projecting axiallyfrom its outer side. The parts 44 and 45 have their surfaces preferablysquared or of irregular form in cross-section to cause them to turn inunison. In using this form of spool the hub portion 44 of the member 42is first inserted within the axial opening of the tape roll 29, being ofsuitable size to fit therein, after which the part 15 of the member 43is inserted within the part 44 from the opposite side of the roll andthe spool with the roll thereon may then be placed between the bearingstandards 82, 32 with the trunnions 4L6 resting loosely in the hearingslots 31.

In lieu of the flat board or core piece which is customarily grippedbetween the ends of the shaft sections 5 for the winding of the goodsthereon in flat form, as is now customarily the case, I provide amandrel 50, of substantially cylindrical form, for such purpose, a corepart 51 of a collapsible nature being first mounted thereon. To permitof an easy insertion of the mandrel into or removal of the same fromwithin the core part, the mandrel is composed of a plurality of partscapable of relative movements to expand or contract the size of themandrel. In the presentinstance, the mandrel is shown as comprising twosections a, a which cooperate to form a substantially cylindricalexterior and are connected in a suitable manner by contractile springs bto normally maintain such parts in collapsed or retracted state.Dowel-pins 0 are also shown as projecting from one of the mandrel partsand working within registering sockets in the other part to guide therelative movements of such part.

52, 52 designate wedge blocks, which are carried by the shaft sections 5at their inner ends (taking the place of the jaws commonly used inmachines of this class for gripping the ends of bolt-boards), the wedgeends of such blocks being intended to removably fit into thecomplemental sockets 53 provided in the respective ends of the mandrel50 between the sections a, 64 thereof, whereby a forcing of the wedgeblocks into such sockets will effect a separation of the mandrelsections and a consequent expansion of the mandrel, as indicated in Fig.9. The surfaces of the mandrel sections with which the wedge blockscoact are shown as being faced with metal strips 54, one of which has anextension 545 projecting without an end of the mandrel to provide afinger-grip to facilitate a withdrawal of the mandrel from a roll ofgoods and its core-piece 51.

The core-piece 51 is composed of any suitable stilf or firm material ofa flexible nature, which is rolled or shaped in hollow form incross-section to permit an insertion of the mandrel 50 therein, thecore-piece being slightly larger in diameter than the mandrel in itscollapsed state for such pun pose. It is found in practice thatcorrugated board with the inner facing strip omitted therefrom, as shownin Figs. 11 and 12, makes a very satisfactory core-piece, as it issufficiently flexible to permit a shaping thereof in circular formwithout breaking its outer surface or crinkling its inner surface, andis at the same time sutliciently stiff to form an excellent core-boardor member when collapsed or flattened for such purpose. It is apparentthat this makes an exceedingly cheap core-piece, which can be thrownaway when once used, or repeatedly used if desired; and that, inaddition to very materially facilitating a winding of the goods in bothform, obviates the use of the customary wooden bolt boards, which arecontinually becoming more expensive due to the growing scarcity of wood.

The operation of my improved goods rolling machine and the carrying outof my improved process of rolling the goods first in circular form andthen collapsing the same in flat bolt form is as follows: The operatorafter placing a core-piece 51 over a mandrel 50, places such mandrelbetween the expanding blocks or wedge members 52, 52, carried by theshaft sections 5, 5, with the mandrel sockets 53 in register therewithand then turns the screw 7 to move the attached shaft section 5 towardthe other shaft section to effect a consequent forcing of the wedgeblocks 52 within the respective mandrel sockets to expand the mandrel toentirely fill the encircling core-piece so that the mandrel andcore-piece will rotate in unison upon operating the machine. This havingbeen done the operator places a tape roll 29 within the bearing arms 32,32, if one is not already positioned therein, and passes the tape overthe set of rolls 3a and channel strip 10, and thence down through theopening in the guide bar 9 and attached part 41 between the folds of thegoods being rolled to pass therewith under the drum 2 and thence to windtogether upon the core-piece carried by the mandrel 50. When the tapehas been positioned in this manner the cappiece. or arm 25 is loweredand secured in position to close the top of the channel strip 10 and thespring bar 38, carrying the set of tape guiding rollers 35, is loweredin the closed position shown in Figs. 2 and 7 with the rollers carriedthereby projecting down between and alternating with the cooperatingguide rolls 34. \Vhen the length or bolt of goods has been entirelywound upon the receiving core-piece 51, the shaft sections 5, 5 arerelatively moved by the screw 7 to permit a removal of the mandrel 50and sur rounding parts from the machine. The release of the expandingblocks 52, 52. from engagement with the mandrel permits the sectionsthereof, under the influence of the contractile springs b, to collapseor recede from expanded relation, thus releasing the mandrel from withinthe core-piece to permit an easy withdrawal of one from the other. \Vhenthe mandrel has been withdrawn from the corepiece the operator pressesupon the bolt to collapse or flatten the core-piece and goods woundthereon in the form shown in Fig. 12. During the winding of the goodsupon its core-piece the measuring tape, which is wound with the goods,is caused to gradually change its position lengthwise of the roll by theaction of the multiple groove cylinder 15 upon the guide strip 10 thusdistributing the tape over a predetermined area of the rolllongitudinally thereof to prevent a noticeable bulging of the roll dueto the thickness of the tape.

I wish it understood that my invention is not limited to any specificconstruction or arrangement of the parts except in so far as suchlimitations are specified in the claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is,-
